GEO4B resit June 2013

Think about the obvious hints they're giving you that they could ask questions on, like 'some people think there may be some links between the trends shown in the two sets of data' (that question is SOOO happening), and then work out how to answer it. For that one, you might need to do some statistical tests and work out a model answer for why temp increase could cause increase in extreme weather, but also reasons why there might not be a link (ie P1 is by an insurance company, so they DEFINITELY have a vested interest in extreme weather 'increasing' - they can raise people's premiums, and they could be including teeny tiny floods because they don't specify what a natural disaster is).

Im thinking just a bar graph? This allows you too see a trend, e.g. if the years are getting hotter (shown my the bars height increasing through the years) plus with a bar graph you can include years which dont have data and skill create the graph.

I think the first question will be "What graphing technique would you use to present the data in P2"

I would mention the bar graph and how you can see trends. I would also explain how i would create it and what my axis would be. I would also talk about why it is better than another technique (for this try to think of another technique which obviously wouldnt work like a pie graph.)
One final thing I think I would mention is that there is a lot of talk about P1 & P2 being linked, so by drawing a bar graph you could have it the same scale as P1 and in theory you could 'overlay' the two graphs to make looking for similarities or trends easier...

These are just my thoughts, hope they made sense.

You said that you would create a bar graph and explain how you would do that and what your axis would be.... if you dont mind me asking how exactly would this be / axis names?

What do you mean know youre way around the booklet? Just like where different things are? Is there know actual figures and information that I need to learn for it?

I would put the years on the X axis (across the bottom) in chronalogical order including years which are not in the table like 1999 2000 2008 then i would have the Anomoly +C ( the temperatures) along the Y axis going up to 0.7 probably

I did spearmans rank on P1 & P2, they are not linked whatsoever

I just did this as well and I am amazed I actually managed to get it right this time!

What is the correlation?? Im sure I got 0.045 which is well below the 95% confidence level and so therefore we can not say that there is a relationship between the 2 variables?

I just got 0.075 but I can't say for certain if that is right. It just means that it is closer to 0 so there is a very weak or no correlation between them.

Hi,

I am also doing the christchurch earthquake paper Does anyone have the zigzag booklet or any possible questions that your teachers think might come up?

kinda confused on what http://www.christchurchquakemap.co.nz/ shows and not sure what we are suppose to note from the website... and how it can be asked in a question

On the double page spread with figure p3,p4 and p5 at the very end it says draw your own conclusion?

What have you guys said about it?

I don't think that P2 could be put into a bar graph as both dat sets are continuous, so I would say line graph, having years on the x axis and then the temperature anomaly on the y axis.

got -0.15 for p1 - p2

and 0.317 for p3 - p4

hey im really confused is this the spearman's rank ? how do you work out spearmans rank for p3-p4?
